EFFECT OF CULTIVAR AND GROWING SYSTEM ON THE BIOCHEMICAL COMPOSITION OF SOUR CHERRY (PRUNUS CERASUS L.) GROWN IN LATVIA
A trial was established at the Latvia State Institute of Fruit-Growing to evaluate the effectiveness of woodchip mulch and drip irrigation on sour cherry growth, yield and fruit quality as compared to untreated control trees. Sour cherries are rich in biologically active compounds. Therefore the aim of this investigation was to examine the biochemical content of sour cherry fruits as influenced by growing conditions and cultivar. Fruit of the cultivars Bulatnikovskaya, Desertnaya Morozovoi, Latvijas Zemais, Orlica, Shokoladnica, Tamaris and Zentenes were analyzed for several biochemical characteristics: including soluble solids, total acids, phenolic compounds and anthocyanins. There were significant differences in fruit biochemical composition depending on cultivar and growing method. Fruit of the cultivars Shokoladnica and Desertnaya Morozovoi had significantly higher soluble solids content than the other cultivars. Both cultivars had a tendency to increased soluble solids content in the control treatment. The significantly highest concentra¬tions of the anthocyanins and phenols in the fruits were recorded for the cultivar Tamaris. High contents of phenols and anthocyanins were detected also in fresh fruit of the cultivars Shokoladnica and Bulatnikovskaya.
